Hi,
10 characteristics ? Are you talking about hikashop characteristics ? or custom product field values ?
I doubt that you can have 10 characteristic for a product. That will probably be too much variants.
I would recommend to use custom fields or options instead of characteristics to avoid eating too much resources on your website.
In any case, you should create one or two products like you want and make sure that they are displaying like you want on your front end. Then, once that's ok, you can export them and you will get a CSV which you can copy for the structure of your CSV with all your products.
